Between 1949 and 1990, thousands of people migrated to the German Democratic Republic (GDR) from countries such as Algeria, Angola, Chile, Cuba, Guinea-Bissau, Mozambique, Syria, and Vietnam. Their stories remain largely untold. The exhibition and research project Echoes of the Brother Countries is dedicated to the often overlooked political, economic, educational, and artistic links, as well as the exchange and migration movements between the GDR and other socialist-orientated states, the so-called brother countries.
